Lumileds has extended its successful LUXEON CoB Core Range with a fourth-generation product. Benefitting from Lumileds’ proprietary phosphor development, this new product can offer efficacy of 170lm/W, some 5% better than competitive products.

The company is able to offer the LUXEON CoB Core Range Gen 4 in a very wide portfolio of products with options for custom spectrum specifications. The new LUXEON CoB Core Range has especially attractive specifications in its 90 Colour Rendering Index (CRI) products, since Lumileds has succeeded in closing the efficacy gap between its 80 CRI and 90 CRI LEDs, increasing the 90 CRI performance by 12% over the previous generation.

The range is available in versions with Light Emitting Surface (LES) dimensions ranging from 6.5mm diameter up to 32mm. These LUXEON products are also supplied in various colour-temperature options from 2,200K to 5,700K and with CRI values of 70, 80 or 90.

The CoB products are mounted on square metal-core PCBs which offer up to four times better thermal resistance than competitive parts, enabling manufacturers to use smaller heat-sinks and optics, and thereby to achieve a lower system cost.
